I am a third year PhD student in pure mathematics at UC Berkeley working with Ian Agol. My research interests include low-dimensional topology (mostly 4-manifolds and knot theory) and some symplectic geometry.

Here is my cv (03/22/2024).

- Will visit the University of Zürich, Switzerland, August 2024.
- Will be coorganizing the student 3-manifold seminar (student low-dimensional topology seminar?) at UC Berkeley with Audrey Rosevear, Fall 2024.
- Will give a talk in the AMS 2024 Fall Central Sectional Meeting, University of Texas, San Antonio, September 2024.

- Khovanov homology and exotic $4$-manifolds, with Michael Willis
- Toroidal Hitomezashi Patterns, with Shengtong Zhang
- Slice genus bound in $DTS^2$ from $s$-invariant, to appear in
*Algebraic and Geometric Topology* - Lee filtration structure of torus links, to appear in
*Geometry and Topology* - A succinct proof of Defant and Kravitzâ€™s Theorem on the length of Hitomezashi loops, with Shengtong Zhang,
*Annals of Combinatorics*(2024) - Spectral asymptotics for kinetic Brownian motion on Riemannian manifolds, with Zhongkai Tao
- Spectral asymptotics for kinetic Brownian motion on locally symmetric spaces, with Zhongkai Tao
